100% of Adam's original income = $400
1% of Adam's original income = 400 ÷ 100 = $4
100% + 20% = 120%
120% of Adam's original income = 120 x 4 = $480
100% of Adam's new income = $480
1% of Adam's new income = 480 ÷ 100 = $4.80
100% + 20% = 120%
120% of Adam's new income = 120 x 4.80 = $576
Adam's latest income = $576
Answer(s): $576
